Etymology. Refers to the name of the type locality, treated as a noun in apposition.

Diagnosis. In the females, the lateral spermathecal receptacles are much larger than the medial receptacles. There is a longitudinal cleft between the lateral and medial receptacles. The lateral receptacles extend forwards beside the atria. There is a thick connection between spermathecal receptacles. Atria, including copulatory openings, are close together, directly anterior to the medial spermathecal receptacle and about the same size as the medial receptacle. Abdomen is without large lateral bulges. Palps are narrow, brown, pointed distally, metatarsal tip light brown. Palps are without a covering of long white hairs. There is a faint line of dorsal hairs on L1. Males are much darker colored than females. Clypeus is without a thick white fringe. The tip of cymbium is off-white. Patella, proximal tibia and metatarsus of L1 are off-white. The palp is mid brown and the tibial apophysis is of medium length, pointed, directed away from the palp. Each embolus arises from a large triangular base and forms a partial spiral across the distal edge of the tegulum.

Description. Female: Cephalothorax mid to dark brown. Surrounds of ALE, PME and PLE, darker with a sparse covering of light brown hairs. Pars thoracica without markings. Clypeus narrow, mid-brown, without a fringe of hairs. Chelicerae light to mid-brown not bulbous. Two small, sharp promarginal teeth and one small, sharp, retromarginal tooth. Endites off-white, darker brown at base, labium off-white. Sternum light brown. Dorsal abdomen heart-shaped, light brown with a pattern of darker stripes, in part forming a darker moustache shape in the middle of the surface followed ventrally by a bright light coloured area. Spinnerets light brown. Ventral abdomen light brown with four, longitudinal rows of lighter dots. Palps narrow, brown, pointed distally, metatarsal tip light brown. Palp with a sparse covering of long white hairs. Legs light to mid brown with darker transverse areas. Medium sized spines, L1 similar build to other legs. Epigynum: The copulatory openings are in the centre of a pair of sclerotised atria without distinct, well-sclerotised guides. The atria are placed a short distance anterior to, and in line with, the medial spermathecal receptacles. Each insemination duct includes a long loop extending forwards from the copulatory opening in the anteromedial edge of the guides before moving laterally and posteriorly over the dorsal edge of the spermatheca before connecting close to the broad connection between the lobes. Each insemination duct has a distinct gland placed just after it leaves the atria. The ducts open into the spermatheca from the dorsal surface, close to the broad connection between the lateral and median receptacles. The spermathecae are placed close to the epigastric fold and the receptacles are unequal in size. The lateral receptacles are much larger and extend up the sides of the atria. Fertilization ducts extend from openings in the middle of the dorsal surface of the median receptacles. Dimensions (Holotype): CL 1.2, EFL 0.55, AL 1.45, CW 0.9, AEW 0.85, AMEW 0.55, PEW 0.8, L1 1.6 (0.6+0.2+0.35+0.2+0.25), L2 1.5 (0.5+0.15+0.35+0.15+0.35), L3 1.55 (0.5+0.2+0.3+0.2+0.35), L4 2.05 (0.65+0.2+0.45+0.25+0.5).

Male: As for female, but color much darker and stronger. Without a thick white clypeal fringe. Palp: mid brown, tibia with single sharply pointed apophysis pointing away from the palp. Cymbium off-white. Each embolus arises from a large triangular base and forms a partial curve across and distal to, the distal edge of the tegulum. The base is partially obscured by a tegular shelf. Dimensions (Paratype): CL 1.25, EFL 0.5, Al 1.25, CW 1, AEW 0.95, AMEW 0.6, PEW 0.8, L1 2.25 (0.75+0.35+0.5+0.25+0.4), L2 2.2 (0.7+0.3+0.45+0.3+0.45), L3 2.05 (0.75+0.3+0.35+0.3+ 0.35), L4 2.35 (0.7+0.3+0.5+0.3+0.55).

Distribution and Biology. Collected in pitfall traps in forest on the coastal side of the Great Dividing Range from central New South Wales south through Victoria to Eastern Tasmania ( Fig. 39 ), as a consequence, likely IUCN Red List Category LC.
